Electronic wrist watch having wireless charging function

ABSTRACT

An electronic wrist watch having wireless charging function is provided. The watch includes a body, a watch strap portion, at least one chargeable battery and a wireless charging module. The watch strap portion includes two watch straps respectively connected to opposite ends portions of the body, and used to wear the electronic wrist watch on wrist. The rechargeable battery and the wireless charging module are arranged in the watch-strap portion, and the wireless charging module is electrically connected to the rechargeable battery. The wireless charging module is configured to wirelessly collect external energy to charge the rechargeable battery. With such a configuration of the rechargeable battery and the wireless charging module arranged in the watch-strap portion, capacity of the rechargeable battery can be effectively expanded, and charging process of the rechargeable battery can be effectively simplified, without changing the size of the electronic wrist watch.

BACKGROUND

1. Technical Field

The present disclosure relates to watches, and particularly to anelectronic wrist watch having wireless charging function.

2. Description of Related Art

With the popularization of small size and powerful electronic devices,electronic wrist watches are not only used to show time, but alsointegrated with various auxiliary functions, such as audio playingfunction, near field communication (NFC) identification function, or GPSlocating function. However, with addition of these auxiliary functions,power consumption is also increased. Therefore, expanding the capacityof a battery of the electronic wrist watch and simplify the chargingprocess of the battery, without affecting the size of the electronicwrist watch are several of important aspects in manufacturing.

BRIEF DESCRIPTION OF THE DRAWINGS

Many aspects of the embodiments can be better understood with referenceto the following drawings. The components in the drawings are notnecessarily drawn to scale, the emphasis instead being placed uponclearly illustrating the principles of the present disclosure. Moreover,in the drawings, like reference numerals designate corresponding partsthroughout the several views.

FIG. 1 is a schematic diagram of an electronic wrist watch, according toa first embodiment.

FIG. 2 is a block diagram of the electronic wrist watch of FIG. 1.

DETAILED DESCRIPTION

FIG. 1 shows an electronic wrist watch 100 of the embodiment. Theelectronic wrist watch 100 includes a body 20 and a watch-strap portion30. The body 20 includes a shell 21 and a display unit 22 arranged onthe shell 21. The shell 21 can be made of stainless steel, plastic orother materials.

The watch-strap portion 30 includes a first watch strap 31 and a secondwatch strap 32 respectively connected to opposite end portions of thebody 20. The first watch strap 31 and the second watch strap 32 are usedto wear the electronic wrist watch 100 on a wrist.

In the illustrated embodiment, the electronic wrist watch 100 furtherincludes at least one chargeable battery 40, which is configured tosupply power to function modules of the electronic wrist watch 100. Inthe illustrated embodiment, the rechargeable battery 40 is a flexiblethin-film battery, and is arranged in the watch-strap portion 30. Inother embodiments, the rechargeable battery 40 can be arranged in theshell 21 of the body 20.

In the illustrated embodiment, the electronic wrist watch 100 furtherincludes a wireless charging module 50, which is arranged in thewatch-strap portion 30 and is electrically connected to the rechargeablebattery 40. The wireless charging module 50 is configured to wirelesslycollect external energy to charge the rechargeable battery 40.

In the illustrated embodiment, the wireless charging module 50 includesa receiving coil 51 for collecting wireless electromagnetic energyemitted by a transmitting coil (not shown) of an external power source(not shown). The wireless charging module 50 further includes aconversion module 52 configured to convert the collected wirelesselectromagnetic energy into power having a predetermined voltage tocharge the rechargeable battery 40.

Therefore, with such a configuration of the rechargeable battery 40 andthe wireless charging module 50 arranged in the watch-strap portion 30,capacity of the rechargeable battery 40 can be effectively expanded, andthe charging process of the rechargeable battery 40 can be effectivelysimplified, without affecting the size of the electronic wrist watch100.

FIG. 2 shows that the electronic wrist watch 100 further includes awatch movement 23 and a micro processing module 24 arranged in the shell21. The micro processing module 24 integrates with various auxiliaryfunctions, such as audio playing function, NFC identification function,or GPS locating function, which can fully meet needs.

The display unit 22 is electrically connected to the watch movement 23,the micro processing module 24 and the rechargeable battery 40. Thedisplay unit 22 is configured to display time, residual capacity valueof the rechargeable battery 40, and information of the auxiliaryfunctions. In the illustrated embodiment, the display unit 22 isselected from a group consisting of a liquid crystal display, an organiclight emitting diode display and an E-paper display.

Moreover, it is to be understood that the disclosure may be embodied inother forms without departing from the spirit thereof. Thus, the presentexamples and embodiments are to be considered in all respects asillustrative and not restrictive, and the disclosure is not to belimited to the details given herein.
